R404A must not be treated as a universal drop-in replacement for R22, R502 or another refrigerant. Before servicing or conversion, verify the equipment nameplate, refrigerant designation, compressor compatibility, lubricant requirements and equipment-manufacturer instructions.
Safety and Handling
R404A is stored as a liquefied gas under pressure. Protect the cylinder from excessive heat, direct sunlight, physical damage and improper handling. Store it in a cool, dry and well-ventilated area.
Contact with liquid refrigerant can cause cold burns or frostbite. A substantial vapour release may displace oxygen, particularly in low or enclosed spaces. Handling, charging and recovery should be performed by a qualified refrigeration technician using suitable equipment and personal protective equipment.
Do not puncture, burn or expose the cylinder to excessive heat. Refrigerant recovery, transport and disposal must comply with applicable local requirements and the current Honeywell product safety data sheet.

Frequently Asked Questions
What is Honeywell Genetron R404A refrigerant used for?
Honeywell Genetron R404A is used in compatible low- and medium-temperature commercial refrigeration equipment, including cold rooms, freezers, supermarket refrigeration systems, display cabinets, ice machines and refrigerated transport systems.
What is the weight of this Honeywell R404A cylinder?
This Honeywell Genetron R404A cylinder contains 10.9kg, equivalent to approximately 24 lb, of refrigerant.
Which refrigerants are included in the R404A blend?
R404A contains approximately 44% R125, 52% R143a and 4% R134a by weight.
Is R404A refrigerant flammable?
R404A has an ASHRAE A1 safety classification and is classified as non-flammable under applicable standard test conditions. It remains a liquefied gas under pressure and must be handled according to the current safety data sheet.
Does R404A have ozone depletion potential?
R404A has zero ozone depletion potential. However, it has a high published global warming potential, so refrigerant recovery, handling and disposal must follow applicable environmental requirements.
Which lubricant is typically used with R404A?
POE lubricant is typically used in compatible R404A refrigeration systems. The exact lubricant type and viscosity must follow the compressor or equipment manufacturer’s specifications.
Can R404A be used in every refrigeration system?
No. R404A should only be used in equipment designed or specifically approved for R404A. It must not be treated as a universal replacement for another refrigerant.
Can R404A directly replace R22 or R502?
No. Any refrigerant conversion requires professional assessment of the compressor, components, lubricant, controls and manufacturer requirements. R404A must not be added to an existing system without an approved conversion procedure.
